Why do it:

A Building Management System integrates control of HVAC, lighting, metering, and other building services into one platform, giving operators real-time visibility and automated optimisation. It reduces energy waste and improves occupant comfort.

Typical Savings:

• Energy efficiency gains: 10–25% reduction in building energy use through optimisation and automation.

• Maintenance savings: Predictive monitoring reduces unplanned downtime and service call-outs.

• Operational benefits: Improved comfort and productivity, plus easier compliance reporting.

• Example: A site spending £500,000 annually on BMS controlled equipment energy could save £50,000–£125,000 per year.

Typical Costs:

• Rule of thumb: £100-£300 per Point (Inputs & outputs to be monitored or controlled)

• Hardware (controllers, sensors, gateways): £200–£1,000 per device depending on function.

• Software licence/platform: £2,000–£10,000 per site annually (scales with building size and complexity).

• Installation & commissioning: £10,000–£50,000 for a medium industrial/commercial site.

• Ongoing costs: £2,000–£5,000 per year (software, maintenance, calibration, updates).
